> I can't see why I'd want an agent to click around Gnome or Ubuntu desktop but maybe that's just me?

What if you want to develop desktop apps?

I think the killer feature in this release is the background GUI use.

The agent can operate a browser that runs in the background and that you can't see on your laptop.

This would be immensely useful when working with multiple worktrees. You can prompt the agent to comprehensively QA test features after implementing them.
